Zusammenfassung:	To provide a hot press molding apparatus that is able to prevent occurrence of delay fracture in a molded article.SOLUTION: A hot press molding apparatus 1 has a molding unit 4 and a trimming unit 3 and performs molding and trimming on a heated metal plate material 2. The hot press molding apparatus includes an upper die 14 (a first die) having the function of a punch 32 and a lower die 13 (a second die) that performs molding in cooperation with the upper die 14. The hot press molding apparatus includes a die 16 that separates the trimming unit 3 from the molding unit 4 in cooperation with the upper die 14. A side of the upper die 14 has a cooling hindering-unit 62 formed of a space in which the trimming unit 3 is exposed.SELECTED DRAWING: Figure 9 【課題】成型品に遅れ破壊が生じることを防ぐことが可能な熱間プレス成型装置を提供する。【解決手段】成型部４とトリミング部３とを有しかつ加熱された金属板材２に成型とトリミングとを行う熱間プレス成型装置１である。パンチ３２の機能を有する上型１４（第１の金型）と、上型１４と協働して成型する下型１３（第２の金型）とを備える。上型１４と協働してトリミング部３を成型部４から分断するダイ１６を備える。上型１４の側方には、トリミング部３が露出する空間からなる冷却抑制部６２が形成されている。【選択図】図９
